    S-Plan redesign for ufh, buffer tank, dhw, heat pump /with solar

    I have looked at the S-PLAN wiring diagram (standard) for my new UFH/DHW system, but I don't think it offers me the best use of the new heat pumps resources, given i want to run the heat pump at low temp for a long time during sunlight hours only. Instead I came up with different control plan...

    Air to Air heat pump

    Has anyone installed / worked with air-to-air heat pumps? I wonder if their running cost is also high? There’s no information on running cost and even the people handling the funding pots for Air source heat pumps, are not aware of the costing.
